- Room Cleaning First Second Third Fourth Fifth 01 2 0 03 Aisha's Willingness to Pay Sara's Willingness to Pay $8 $7 $6 $5 $4 $10 $8 $6 $4 $2 Aisha and Sara are roommates who both benefit from having their room cleaned by a cleaning service. The table shows their individual willingness to pay for each room cleaning. The marginal cost of each room cleaning is $16. Considering that both roommates benefit when the room is cleaned, what is the efficient number of room cleanings per week that maximizes total surplus?Say that you are a manager with the Transportation Security Administration (TSA). The table below shows fictional estimates of the marginal benefit and marginal cost of additional TSA security lines at Mahlon Sweet Field, the airport in Eugene, Oregon. Number of Marginal In this space, draw the graph of the marginal data from the left columns. Answer these questions below using the data table and graph. Benefit 3. Security Lines 1 2 3 4 5 6 $10,000 9,000 7,000 5,000 4,000 3,000 Marginal Cost $2,000 3,000 4,000 5,000 8,000 12,000 The surplus of the marginal benefit over cost for the second security line is $ and $ for the third security line. If your goal is to maximize total surplus, you WILL / WILL NOT (circle one) operate a third security line. The optimal number of TSA security lines is because this is where the marginal equals the marginal which maximizes totalSue Tom Good A 10 4 Select one: Good B 15 5 As shown in the table above, Sue and Tom each can produce two different types of goods. For Sue, if she only produces Good A, then she can produce 10 units of Good A per day. If she only produces Good B, then she can produce 15 units of Good B per day. For Tom, if he only produces Good A, then she can produce 4 units of Good A per day. If she only produces Good B, then she can produce 5 units of Good B per day. Which of the following statement is correct about comparative advantage? O a. Tom has a comparative advantage over Sue in the production of Good A. Sue has a comparative advantage over Tom in the production of Good B O b. Tom has a comparative advantage over Sue in both tasks O c. Sue has a comparative advantage over Tom in both tasks O d. Sue has a comparative advantage over Tom in the production of Good A. Tom has a comparative advantage over Sue in the production of Good B
- 3. The Centers for Disease Control and Prevention (CDC) has a new vaccine against a disease and are trying to determine the optimal percentage of the population that should be vaccinated. They do not recommend vaccinating the whole population against the smallpox virus because the vaccine has undesirable, and sometimes fatal, side effects. Suppose the following table gives the data about the effects of the vaccine. a. Calculate the Marginal Benefit (in terms of how many extra lives are saved by the vaccine) and the marginal cost (in terms of how many extra lives are lost due to side effects) of each 10% increment of the vaccination. Write your answers on the appropriate columns above. b. Using marginal thinking, determine the optimal percentage of the population that should be vaccinated. Explain your answer.1. Road construction is going on Riccarton Road. 100 Uber drivers want to drop their passengers at the airport. Each driver is deciding whether to take Riccarton Road or take Blenheim Road. The cost of travelling through Riccarton Road is $10 (additional fuel required due to slow traffic), while the Blenheim Road route has a low fuel cost (theoretically let's assume $0) but takes more time to reach the airport. In deciding on a route, each driver cares only about income, denoted i, and his travel time, denoted t (where we have made the dollar value of one unit of travel time equal to 1). Driver's payoff is assumed to be his/ her profit (income - cost of travelling, including travel time). Assume that each driver has same income of $500. If m drivers are on Riccarton Road, the travel time for a driver on Riccarton Road is assumed to be m (in dollars). In contrast, if m drivers take Blenheim Road, the travel time for those on the Blenheim Road is 2m (again, in dollars). Drivers make…4 Jill and Jack both have two pails that can be used to carry water down from a hill. Each makes only one trip down the hill, and each pail of water can be sold for $5. Carrying the pails of water down requires considerable effort. Both Jill and Jack would be willing to pay $4 each to avoid carrying one pail down the hill, and an additional $4 to avoid carrying a second pail down the hill. nt a. If Jack and Jill each must decide whether to carry one or two pails of water down from the top of the hill, how many pails will each child choose to carry? pail(s) b. Jill and Jack's parents are worried that the two children don't cooperate enough with one another. Suppose they make Jill and Jack share equally their revenues from selling the water. Given that both are self-interested, construct the payoff matrix for the decisions Jill and Jack face regarding the number of pails of water each should carry. Instructions: In the payoff matrix below, enter the payoffs for each child for each…

Voluntary contributions toward a public goodLarry and Raphael are considering contributing toward the creation of a public park. Each can choose whether to contribute $400 to the public park or to keep that $400 for a new suit.Since a public park is a public good, both Larry and Raphael will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.80 of benefit. For example, if both Larry and Raphael choose to contribute, then a total of $800 would be contributed to the public park. So, Larry and Raphael would each receive $640 of benefit from the public park, and their combined benefit would be $1,280. This is shown in the upper left cell of the first table.Since a new suit is a private good, if Larry chooses to spend $400 on a new suit, Larry would get $400 of benefit from the new suit and Raphael wouldn't receive any benefit from Larry's choice. If Larry still spends $400 on a new suit and…Suppose that there are only two fisherman, Zach and Jacob, who fish along a certain were built along the coast. They would each benefit if lighthouses were built along the coast where they fish. The marginal cost of building each additional lighthouse is $100. The marginal benefit to Zach of each additional lighthouse is 90-Q, and the marginal benefit to Jacob is 40-Q, where Q equals the number of lighthouses. a. Explain why we might not expect to find the efficient number of lighthouses along this coast. b. What is the efficient number of lighthouses? What would be the net benefits to Zach and Jacob if the efficient number were provided?
